A guidance counselor wants to determine if there is a relationship between a student’s number of absences, x, and their grade po
int average (gpa), y. The data that were collected are displayed in the scatterplot and the least-squares regression line was calculated. One student with 2 absences has a gpa of 1. 8. This point is circled on the graph. What effect does the circled point have on the slope and y-intercept of the least-squares regression line? this point will increase the value of the slope and increase the value of the y-intercept. This point will increase the value of the slope and decrease the value of the y-intercept. This point will decrease the value of the slope and increase the value of the y-intercept. This point will decrease the value of the slope and decrease the value of the y-intercept.
Based on the information given, the effect of the circled point on the correlation will be D. This point will decrease the value of the slope and decrease the value of the y-intercept.
<h3>What is correlation?</h3>
From the complete information, it can be noted that the effect of the circled point on the correlation is that the correlation will be weakened because the point falls outside the data pattern.
Therefore, this implies that the point will decrease the value of the slope and decrease the value of the y-intercept.
